wrap(View)，父为LinearLayout时，会导致View总是最后一个

```kotlin
@JvmStatic
fun wrap(view: View): StateView {
    val parent = view.parent
    if (parent is ViewGroup) {
       ...
        val wrap = FrameLayout(view.context)
        // 似乎应该处理 index
        parent.addView(wrap, view.layoutParams)
        ...
        return stateView
    }
    throw ClassCastException("view.getParent() must be ViewGroup")
}
```
